Translocation as a tool for the conservation of the jaguar Panthera onca: a case study in the Brazilian Atlantic Forest

Abstract

The success of translocation as a management tool is based on reversing the factors that led to a population becoming threatened or locally extinct. We assessed whether translocating a jaguar Panthera onca into the surroundings of a protected area in the Brazilian Atlantic Forest with a resident jaguar population was effective. We captured a male jaguar in an urban area where there were no substantiated previous records of jaguars. In the capture area only one predation event had been recorded, when the jaguar killed several chickens a few days before capture. After capture we translocated the jaguar to a forested area 240 km from the capture site, adjacent to the Rio Doce State Park. To investigate whether the potential geographical origin of the individual was any nearby fragment of the Atlantic Forest or nearby fragments of the Cerrado ecoregion, we genotyped it for 12 microsatellite loci and compared the results to a database developed previously. We fitted the jaguar with a GPS/VHF collar from which we recovered 2.5 months of data. Post-release monitoring with camera traps indicated the jaguar established residence within the region of the Park and we recorded no events of predation on livestock. The genetic analysis indicated that the jaguar resembled individuals from the Inner Atlantic Forest, Cerrado and Amazon. Translocation was an important tool for avoiding potentially negative interactions between the jaguar and local people, and may have benefitted the jaguar population at the release site.
